Application filed September 16,1907. Serial No. 392,994.

To all who/m it may concern:

`Be it known that I, JOHN M. Bnoon, a citizen of the United States, anda resident of New York, county and State of New York, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification.

llf'lyfinvention relates to heatingand coole ing apparatus; and while it may be embodied in constructions adapted for Various purposes, it is more particularly applicable to stoves and stoves consuming iiuid fuel.

' Objects of the invention are to provide a novel construction of gas stove which shall contain an incandescent member; which shall in operationbe free from objectionable odors and deleterious products of combustion; which shall have its parts efiectively Vand compactly arranged; which shall be, economical in construction and operation; and' to provide a construction of the character described which shall be neat in apj'ieai'ancc and particularly attractive inA use. These and other objects of the invention will 1n part be obvious and 1n part be lmore fully 'explained in the following description.

My ii'ivention,consists in the novel parts, improvements, combinations and features of construction herein shownand described.

The accompanying drawings, which are referred to-licrcin and form a'part hereof, illustrate one embodiment of the invention, the same serving in connection with the de: scription herein to explain the principles thereof.

Of the dran-"ings: Figure l is a vertical central section of a gas stove constructed in accordance with certain features of the invention;` Fig. 2 a plan view of the same taken on the line 2-2 of Fig. l; and Fig. 3 is another plan view of the same taken on the line 3- 3 of Fig. l.

A stove constructed in accordance with certain features of my .invention comprises in combination a hollow, rigid member forming within itself a combustion cliambc and adapted to be heated to incandcscence, 'a burner constructed and arranged to'admit it is vented at its top, the top preferably being open; it is perforated or reticulated; it is formed ot' a metal. adapted to be heated to incandescence, preferably cast iron; it is incloscd within a casing; it is connected ywith a diaphragm, preferably imperforate, which divides the casing into two compartments or portions, in the upper one of which the incandescent member is located while the burner is located in the other, the lower portion of the casing being constructed to admit unheatcd air andthe upper portion of the casing being constructed to discharge heated air. According to still other features of the invention means are provided for detlecting the heated air on leaving the combustion chamber; the burner is provided with means for mixing air with the fuel supply; and in thel top of the stove is located a grill, and at the bottom means for preventing radiation of the heat to the floor. These and other features of the invention D will be more fully explained in the following description.

Referring now to the. drawings in detail, the cmbodimentof the invention illustrated Icon'iprises an outer shell or jacket 1, which is `mounted upon a base 2 having legs 3. At a suitable distanceabove the base is located a burner .4., having a fuel supply tube i5. Further reference to the burner will be hereinafter made. I

An important feature of the invention resides in-the provision of means for perfeeting and augmenting combustion, therei by serving the two-fold purpose, alnonfr others, of greatly increasing the heating ef:- ficiency of the apparatus and consuming dangerous gases and elin'iinating disagreeable odors and other objectionable features incident to constructions of this character. 'lylule this feature may be embodied 1n various terms and niaterials preferably and as shown, there is provided a hollow member formino within itself a combustion eham bei', said member being,` adapted to be heated to incandescenee.l This incandescent inember may be of any suitable .material and may be located in any suitable place in the'stove. Preferably and as shown however, said member is formed of metal, sheet or east, and is situated above the burner 'Where it is subjected to the heated air andproducts of combustion which pass along its inner surface and heat it te incandescente, By rea:- son of its ineandeseenee said member insures the complete combustion of all combustible `gases or vapors,

While the incandescent n'iernbe-r may take any suitable shape or be of any desired. size to perform said functions, preferably and as shown it made in the form of a hollow upwarilly tapering nieu'iber or cone7 thereby eonforniingg,v approximately to the natural shape of the: heated ga arising from the burner. To aid in bringing said ineandescent member to a state of incandeseenee, if.. is perforated to bring,- about a more inti- .inate Contact of the llame and the heated gases with the heated member and also to in ere-ase the area ol? the heatedinember with which the gases and llame come in Contact.

i ln the preferred embodiment, as shown, the

member vis perforated` with numerous' per` foi-ations throughout the greater part of its area.

'lhe burner l may be of any suitable sire and form oil' construction adapted to concentrate thecoml'uistion substantially within the chamber formed by the incandescent. member so as to heat said member to a low ineandescence without. the consumption of an undue quantity of fuel; lzreferably, and as shown7 it is annular in shape and has an outer ring 'i' in an inner ring` between which parts openingis4 are provided for the admission of air to the eolnl'uistion ehambervindependently of the fuel, the burner being preferably interspaced from the ineandes# cent member so as to ailord an opening for admission of air between these parts. The 'outer ring is preferably so situated With re; speci' to the incandescent member and has its outlet openings for the fuel or mixture of fuel and air .so-arranged that the flames will form a ring;r and be directed toward the 'lower .inside surface of said combustion chandler so as to annly the heat to the member (l 1n an el'ticient manner. While themnerring may have its outlets for the fuel i disposedv in various ways adapted to aecomy plish the vdesired resulty as shown, they are disposedso that the flames will extend upwardly and outwardly in a direction tending to meet the flames of the outer ring at v l points yadjacent to the inner surface of the member (l.

lt 1s to be understood that. my invention since the burner may be adapted for-the use of oil or various fluid fuels, ifd'esired.

n the preferred form of'the invention, and as shown,.suitable means are provided for mixing air with the fuel supply, the same consisting of a Bunsen mixing chamber 9, preferably situated without the easing adjacent to the base thereof,

tion resides in the provision of means for naa-intainingperfect combustion. lf the heated air is allowed unduly to reniain in the Combustion chamber, theintalte of fresh air to support combustion is preyci'itecij and carbon monoxid is `ivan olf. ',lo obviute this defect, provision is made for the free passage of the heated `air from the combustion chamber. While this may be accomvided, preferably, in the top of the combustion chamlur. rlhe heated v air passing through this vent Aand through the perf-oran tions in the walls of the Combustion i'fl'iamben air enters through spaces between vthe inner and outer rings Y and 8 of the burner. By passing through the Walls of flame on the said rings such of the air as is not taken to support Combustion in the said walls of llame enters the combustion chamber in a super-heated condition, thereby facilitating the consumption of any combustible gases or vapors with .which it unites in the4 chamber formed by the incandescent member. ln order that the d1 aft may not become execs sive and permit the heated products of coin- ,bustion to pass out of the combustion chamber before perfect combustion has taken plane, suitable means are provided for regulating the draft., the saine, in the preferred forni of the invention and as shown, taking the form of a deleetor which serves to deflect downwardly the heated air issuingv from the combustion chamber. This deflecytor is preferably located above'the combustio'uchamber, being` situated-at any suit able distance from the same and being` of any suitable shape. Preferably and showin'I a dome-shaped dei'leotor `l() is proL place by being fastened to the member G by means of lugsw'll. l2 is also provided in the preferred embodiment of the invention, the same preferably being also dome #Sha ed and located above hangers 13. yThis deleetor preferably ein tends over the entire areaA embraced Within the outer shell l. lf desired, one only of the is not limited to the use ofgas as a fuel,-

a strong' draft isqseeured and atmospheric vided, the same being preferably held in.

thefirst deleetor an being 'preferably suspeuded from the top of the outer shell l by c nother important feature of the inveni,

plislied in any suitable vay, preferably and f as shown. a vent of any desired size is pro- An additional dellcctor y' f same time cause the heated gases to leave trated in the drawings the shell is shown rthroughoutthe entire extent of the shell.

deflectors may be used, preferably the detiector 10.

One important function performed by the delectors in connection with the incandescent'nlember is the radiation of the heat nea-rt-he floor, where it is most needed. The deflectors not-only make it ossible to keep the member 6 in an incan( escent state so that the heat will be radiated but they serve to prevent thefupward radiation and at the the stove in a lateral direction instead ot' rising rapidly to the'upper part of the room in accordance with their natural tendency.

An important feature of the invention consists in providing means for preventing the cold air which enters the stove at the burner from4v rising into the chamber formed, by and between the outer shell 1 and the: outer surface of the chamber 6. 'While this may be accomplished in any suitable way, for instance by so shaping said incandescent member that its loweredge will extend outwardly to the shell 1, preferably and as shown, an im erforate flange or diaphragm 14 is provide the same extending from the combustion chamber at a point preferably below Where the flame impinges on said chamber to the outer shell and thus dividing said shell 1 into two compartments. Said flange is, preferably and as shown, fastened to the outer shell and also affords means for supporting in osition the member 6, in the preferred em odiment illustrated being made an integral part thereof. l

Another important feature of the invention consists in providing means whereby a view may be had of the incandescent member 6, which, when in a state of incandescence, resents a strikingly attractive and cheerfu appearance. Thls may be done inany suitable way, as, for example, by making suitable apertures or perforations in the shell. It will also be seen that the outer shell orjacket 1 may be made in a Variety of forms and shapes in which the incandescent member maybe displayed and protected from excessive drafts of cold air and which forms and shapes may be so designed as to add greatly to the attractiveness and clieerfulnessof the stove, especially when in use.

In the embodiment of the invention illusas perforated,

extending being cylindrical in form and the perforations preferably The perforations and apertures serve `the further purpose of providing a passage for the heat radiated from the member 6 and the heated air in the upper compartment into the surrounding atmosphere. The perforations in the outer shell l, extending below' the diaphragm 14 will also permit the passage of air to the lower compartment of the many changes may be mad stove, where it will support `combustion in the flames of the rings 7 and 8 of the burner, from whence it will be drawn upwardly between the rings of the burner and maintain combustion, as heretofore explained. To prevent radiation of heat downwardly, a suitable bottom is provided for the stove, the same, preferably and as shown, consisting of metal plates lo and 1.6,.between which is a layer of asbestos 17 or similar material. The stove is also provided with a removable top 18, the same preferably andas shown consisting of two sections, in the lower of which sections is contained a grill 19 for cooking, the upper section 20 preferably being ornamental in character.

While the various parts of the stove may be held together in any suitable way, in the embodiment illustrated two rods 21 extend through the stove near the. shell, being secured at the top and bottom. l

Itwill be seenthat by reason of the construction shown and described a form of gas stove is provided which is simple and compact, neat and cheerful in appearance economical in construction and operation, whose parts are easily duplicated, and which is adapted for the use of other fluid fuels.

Advantages other than those heretofore set forth will be apparent to those skilled in the art.

It is to be understood that my invention in its broader aspects is notlimited to the i prcclse construction shown nor to any particular construction by which the invention has been or may be carried into effect, as e in the details of the parts without departing from the main principles of the invention and without sacrificing its chief advantages.
